CS175 clutch - help please.

Hi all,
My CS sport clutch is slipping in top, so I've pulled it apart - see photos below. In general it doesn't look too bad so I'm unsure what to do to solve the problem. New pressure plates, or new friction plates, or new springs OR ALL 3!
Pressure plates probably look the worst due to pitting.
Clutch has 4 x friction and 4 x pressure plates. Is this correct?
Suggestions please?

The steel plates are probably OK in spite of pitting, as long as they are flat and meet thickness specification. Friction plates are likely worn or glazed. There is a thickness specification for those as well....somewhere. I don't have it.

Springs can cause slipping in higher gears as they lose tension. There should be a free length spec to measure against. Your pressure plate (the one that the springs push against compressing the plate stack) looks fine.

I'd be seeking new friction plates and springs. But if you find those and new steels as well it would be smart to get them all and start fresh.

Just a quick note....wet motorcycle clutches don't do well with some modern oils. Friction modifiers will make them slip. Be sure to use a MA or MA2 spec oil.....no "energy conserving oil" allowed, ever.

I used to be fast....now I just dream about it.
